While at a business event, my upper left side of lip became a bit numb, and when I spoke, my mouth didn't move as freely. Sort of like a very mini-mini-mini stroke victim, that you wouldn't even notice if you didn't know me. 3 hours later, it seems much better, and is the ONLY symptom I had. No pain, no tingling, no issue other than feeling a little as if novacain had been applied to that one small section just at top of my left upper lip. Thanks for whatever guidance you can give me.
